Metal strip power resistors provide low resistance values and improved TCR

New Yorker Electronics has expanded its metal strip power resistors by now supplying the entire line of VPG Foil Resistors. The newest addition, the VPG CSM Product Family of Two-Terminal Current Power Resistors, provides users increased accuracy and repeatability under high-stress conditions.

The resistors are employed for medical and automatic test equipment, power amplifiers, communication systems, high-current applications for the automotive market and others. Each possesses a resistance tolerance to ±0.1% and a working temperature between -65C to 170C. The CSM relies on proprietary techniques to produce low resistance values and improved TCR.

There are a variety of options in the CSM Series of Current Power Resistors:
